Dec 24, 2016 · Wire-cut EDM is used to produce complex-shaped and delicate parts; however, surface roughness (SR) is entirely dependent on optimal combination of input process parameters which is a difficult task. In this research, surface roughness model has been developed for high-strength low-alloy (HSLA) steel (30CrMnSiA, 38HRC).
